Temperature Control

Summer is here, and with it comes the hotter days. As a grower, dealing with these hot temperatures in the grow room can be an ongoing battle that is a hard one to win. These hot temperatures will cause an increase in water and air temperatures which can both be extremely detrimental to plant growth and development.

When growing in soilless hydroponic systems water temperature is just as important as the temperature of the rest of your room. When the temperature of the nutrient solution in your system is too low, plants will struggle to uptake and processes will slow to a halt. Too high a temperature decreases the oxygen content within the water, and creates an ideal environment for anaerobic organisms to thrive such as Pythium that cause root rot, disease and in worst case scenarios will kill your plants. Using a water chiller to cool your nutrient solution will prevent the loss of oxygen and will stave off the harmful organisms. Optimal water temperature is around 18 Celsius, anymore than this the oxygen content will start to decrease to levels that can be hazardous.

When it comes to maintaining good air temperature within your grow room, air conditioning units are the most effective way to create source of cold air. On the other hand they are not cheap to purchase or to run, and also create a large amount of excess heat that needs to be deposited away from your grow area.

Without the use of air conditioning units there are a few products that can help you get through the hot and trying summer months helping you to deal with temperatures in excess of 30 degrees Celsius. The addition of extra carbon
